1 Claim.

The present invention relates to improvements in dispensers for liquidsand pulverulent materials of the type wherein the material to bedispensed is held within a closed, resilient and compressiblereceptacle, from which it is adapted to be sprayed or discharged insmall, measured quantities by compressing or squeezing the receptacle.

Receptacles of the character mentioned are ordinarily in the form ofbottles and serve to store toilet preparations, deodorants,disinfectants and the like. They are commonly made of plastic materials,preferably polyethylene. While for ordinary use the shape or design ofthe container is immaterial, its beauty or elegance is essential in casethe container is to be placed on a dressing table or, as a matter offact, into almost any room of the living quarters of a house. Squeezablepolyethylene bottles do not lend themselves to relief ornamentation, as,for the purpose of obtaining the necessary degree of elasticitythroughout the length of the bottle, it is essential that itscross-section at right angles to its longitudinal axis be uniform, andthat its wall be thin and even throughout.

The main object of the present invention is to produce an ornamentaldispenser of the type mentioned, which is composed of two sections, adecorated housing and a plain, squeezable receptacle, the formerincasing the latter and cooperating with the same in dispensing thematerial contained in the receptacle.

Another object of the invention is to so construct the two elements ofthe dispenser that they are held together by friction only, that iswithout the use of special locking means or the like.

With these and other objects in view, which will more fully appear asthe nature of the invention is better understood, the same consists inthe combination, arrangement and construction of parts hereinafterdescribed, pointed out in the appended claim and illustrated in theaccompanying drawings, it being understood that many changes may be madein the size and proportion of the several elements and details ofconstruction within the scope of the appended claim, without departingfrom the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated inthe accompanying drawings, in which:

Figure 1 is a front elevation of a dispenser constructed in accordancewith the present invention;

Figure 2 is a section taken on line 2-2 of Fig. l;

Figure 3 is a top elevation of the improved dispenser;

Figure 4 is a front elevation of the receptacle element of thedispenser; and

Figure 5 is a section taken on line 5-5 of Fig. 4, on a larger scale.

In the drawings, the numeral l6 indicates the housing as a whole, andthe numeral I l the receptacle as a whole. The housing comprises a basel2, from which rises an open casing l3 consisting of a front [4, alongthe entire perimeter of which is formed a continuous wall l5, extendingat right angles to and rearwardly of said front. The housing may be madeof any suitable rigid material, preferably a plastic substance. It maybe ornamented in any suitable way. In the case illustrated in thedrawings, the front wall is circular in configuration and the continuouswall, consequently, cylindrical, but it is obvious that the said frontmay be of any other configuration, for instance polygonal, in which casethe wall l5 will be of prismatic design. In either case, the casing I3is closed at its front and open at its rear.

For decorative ends, the front I5 of the casing, with therepresentations of fins l6, tail l1 and eye I8, presents a conventionalfish, but it will be readily seen that any other suitable decorativescheme may be made use of, without departing from the invention.

In the top portion of the wall I5 is formed a recess l9, extending fromthe open end of the casing toward the front It thereof, but stoppingshort of the latter.

The receptacle II is, preferably, formed of polyethylene and comprises afront wall 20 and a rear wall 2|, the configurations of which correspondto that of the casing front l4, they being circular. These walls areconnected by a wall 22, corresponding in configuration to that of thecasing wall l5, it being cylindrical. On the wall 22 is formed a neck23, fitting the recess IS in the casing wall 15. The neck is closed by adisk 24, provided with a minute discharge opening 25, around which isdisposed, interiorly of the receptacle, a spray tube 26, which extendsfrom said disk toward the bottom of the receptacle, stopping short ofsaid bottom. The disk 24 is attached to the neck 23 and the tube 26 tothe said disk in a manner so as to provide air-tight connections.

The thickness of the receptacle walls is held within limits to producean easily squeezable and compressible structure.

From the rear wall 2| of the receptacle projects a flange 21, disposedin the plane of the said wall and serving as the means by which threceptacle is handled when it is to be inserted into the casing l3. Tofacilitate such insertion, the outer surface of the receptacle wall 22is tapered toward the front wall thereof, the two circles A and B inFig. 4 indicating the extent of the taper. If found necessary, the innersurface of the cylindrical casing wall I5 may be tapered accordingly.

After the receptacle has been filled with the desired liquid orpulverulent material to a height a substantial distance below its neck23, to provide an airspace therein, the disk 24, with the tube 26depending therefrom, is aflixed, for instance, by a suitable cement tothe receptacle.

The filled receptacle is then inserted into the casing l3, it beingforced through the open rear end of the latter, with the neck 23 inalignment with the recess IS in the casing wall [5, toward the front Mof the casing. In forcing the receptacle into the casing, care must betaken so as not to compress the receptacle. The flange 21 on thereceptacle serves as a handle, by means of which the receptacle may begrasped by the fingers of the operator in assembling the elements of thedispenser without the danger of squeezing the receptacle walls. Thereceptacle, due to the close fit between it and the casing, is held inthe casing by friction.

For the purpose of the spraying the contents of the receptacle, thedispenser is taken hold of by one hand of the operator, the thumb of thehand being placed on the rear wall 22 of the receptacle and theremaining fingers on the front I4 of the casing, and the said rear wallforced 35 toward the front wall of the receptacle. The air within thereceptacle is thereby compressed, escaping through the discharge opening25 in the closure disk 24 and carrying with it and spraying or atomizinga small quantity of the receptacle contents. The receptacle returns toits normal form, as soon as the pressure is released thereon.

What I claim is:

A dispenser comprising a rigid housing including a base, a casing risingtherefrom composed of a vertical front and a wall extending rearwardlyfrom said front all around the perimeter of the latter, said wall havinga recess at its top portion running from the open rear end of saidcasing toward said front, a closed, resilient compressible receptaclefitted into said casing from the rear thereof, said receptacle includinga front side, a rear side and a wall connecting said sides, theconfiguration of said sides corresponding to that of the front of saidcasing and the outer face of said receptacle wall fitting closely theinner surface of said casing wall whereby said receptacle is retained byfriction in said casing, a neck on the top region of said receptaclewall fitting the recess in said casing wall, a closure disk attached tosaid neck having a discharge opening, a spray tube fixed to said closuredisk around its discharge opening extending therefrom toward the bottomof said receptacle but stopping short thereof, and a flange on the rearside of said receptacle arranged in the plane of said rear side andserving as the means whereby said receptacle may be grasped by thefingers of the user in assembling said receptacle with said housing,
